FENCE: Uses similar G-hands but typically covers a larger area, often with more distinct vertical posts and horizontal rails, sometimes with a 'walking' movement of the hands. 'Air grating' is smaller, more compact, focusing on a denser grid. PRISON BARS: Often uses G-hands, but usually in a more static, vertical orientation, sometimes depicting holding onto bars, with a more constrained or rigid feel. 'Air grating' has more dynamic, intersecting movements. GRILL (BBQ): Can use flat hands for the grill surface, or a 'fork' handshape for turning food, distinctly different from the G-hand grid of 'air grating'
